Application led July 24, 1918. Serial No. 246,615.

T0 all whom t may concern:

Be it known that we, HARRY C. SILLETT and ALBERT W. COWAN, citizens ofthe United States, both residing at Kansas City, in the county ofJackson and State of Missouri, have invented new and useful Improvementsin Hydrocarbon-Gas Generators and Burners, of which the following is aspecification.

This invention relates to hydro-carbon gas generators and burners and itconsists in the novel features hereinafter described and claimed.

An object of the invention is to provide a burner of simple and durablestructure having means for effectually converting hydro-carbon oil intogas which is consumed at the burner proper and the heat from the flameof the burning gas is utilized as means for transforming the oil from aliquid to a gaseous state.

In the accompanying drawing Figure 1 is a side elevation of the burnerwith parts broken away. l

Fig. 2 is a transverse sectional view of the burner.

Figs. 3 and 4 are detail views of the features of the invention.

The burner comprises a casing 1 consti' tuting a mixing chamber which ismounted upon suitable legs 2. The top portion of this chamber isprovided with a plurality of domes 3 which are spaced from each other byan intervening valley 4. The sides of the chamber 1 and the tops of thedomes are provided with transversely disposed slits 5 through which thegas may emit from the chamber. A fender plate 6 is located at one end ofthe retort and the chamber is provided in its interior and upon itsbottom with a baffle wall 7. A curved pipe 8 is connected at one endwith one end of the chamber 1 and has its other end terminating adjacentthe fender 6.

A pipe 9 is supported above the chamber 1 and extends above the valley 4between the domes 3. The pipe 9 is provided with a spirally disposedcorrugation 10, which extends longitudinally of the said pipe. Theobject in providing the corrugation 10 is to increase the surface of thepipe 9 which is exposed to the flame from the chamber as hereinafterdescribed. A nipple 11 1s screwthreaded in one end of the pipe 9 andPatented July end of the nipple 11: opposite the receiv- .A

ing end of the pipe 8 and is slightly spaced therefrom as indicated inFig. 1 of the drawing. A body 12 is screwthreaded upon the opposite endof the pipe 9 and oil may be let into the body 12 through a nipple 13located at the side of the said body. A stem 14 traverses the length ofthe body 12 and the'pipe 9 and enters the nipple 11. That end of thestem 14 which islocated within the nipple 11 is pointed whereby the saidstem may serve as a needle valve. The stem 14 has screwthread engagementwith the body 12. The stem 14 is provided at its outer end with alaterally disposed handle 15. A wick 16 is coiled around theintermediateportion of the stem 14 and is housed within the pipe 9. The wick 16 liscomposed of strands of wire twisted together and the said wick serves asmeans for retarding the passage of the oil through the pipe 9.

The operation of the burner is as follows Assuming that oil is admittedinto the pipe 9 through the body 12 and that the stem 14 is at an openposition with relation tothe nipple 11 the oil passes through the pipe9. `When the pipe 9 is heated the oil is transformed from a liquidcondition to a gas and the gas flows through the nip* ple 11 and mixeswith the external air and this mixture passes into the pipe 8 and fromthe pipe into the chamber 1. The baffle plate 7 directs the mixtureupwardly toward the slit 5. The mixture passes through the slit 5 whereit is ignited at the outer surface of the chamber 1, and consequentlythe pipe 9 is enveloped in flame and this supplies the heat to convertthe hydro-carbon from a liquid to a gas.

From the foregoing description taken in conjunction with theaccompanying drawing it will be seen that a hydro-carbon y burner ofsimple structure is provided and that the same may be economically usedfor employing a hydro-carbon gas for heating purposes and the flamewhich supplies thev heat is used for converting the hydro-carbon oilfrom a liquid to a gas.

Having described the invention what is claimed is A device of thecharacter described comprising a casing constituting a chamber, the topof said casing having its side portions formed as domes separated by alongitudinal valley, the top ot said casing and domes 1oeing slit toVprovide burner openings, a4

plate at oneend of said easingV extending thereabove a curved 1 ecommunicating 7 C lat its lowery end with one end of said casing andhaving its upper end terminating adjacent said plate, a nozzle carriedby said Y plateY in alinement 'with the upper endv of said pipe, aretort pipe supported above `10 Said valley and connected andcommunioatngWYWt-h said nozle, a fuel Ysupply' pipeY leading intoV saidretortpipe, and a stem extending' longitudinally through said retortpipe and movable to regulate the open- HARRY C.
